Our results were not done using a 30 minute oil out run, but a 2 hour aux lube test, based on our transmisson design. After completion of all testing, the power gears and most accessory gears were Magnetic Particle Inspected, with no defects found on any teeth. Visual inspection of the power...
Geesamand your gear cutters may well be right. They probably can grind, hone and polish to an Ra of 4, but why? This requires they to do it tooth by tooth, gear by gear. To achieve this surface finish conventionally is both time consuming and expensive. superfinishing is a batch process...
To all:
I have personally and actively been involved over the past four years working to qualify the REM ISF process for use on Army helicopter platforms. Bottom line: this process works.
In every test performed to date, and there have been many, each with hundreds of hours of very demanding...
Proprietary data exist showing an increase in fuel efficiency, which makes pretty good sense when you think about it. ISF reduces friction loss, allowing the drivetrain to operate more efficiently, thereby consuming less fuel.
The REM process known as Isotropic Super Finishining (ISF), has proven itself in the automotive racing industry already and is currently proving itself beneficial for helicopter transmissions as well.
As one of the folks working to implement this technology within the military helicopter...
